DR NEONsâ„˘ are super-bright color coated strings that sound clear, bright and musical. Players love the bright NEONâ„˘ colors and their remarkable sound. Super bright in daylight and under stage lighting, DR NEONâ„˘ is 100% black light reactive and glow strongly under UV lighting. NEONs are the first coated string to make no apologies. While Neons last as long as a coated string should (three to four times as long as uncoated strings) they sound as good, or better, than uncoated strings.
